Hippy: Sorry to hear of your loss of the XR-100!
I love those Rifles and own 5 XR-100's including 3 in caliber 204 Ruger.
I have a lifetime supply of these fine guns in 204 and actually plan to bequeath one each to my 3 sons when the time comes.
I bought all of my XR-100's through F.F.L. dealers so I hope I do not have your missing XR-100 in my collection if you would like to forward me your missing XR-100's serial number I will double check.
By coincidence a young man my middle son went to school with had an XR-100 in 204 Ruger stolen from him year before last along with its Zeiss scope. He was a Bakken oil range worker and it was stolen from his truck.
Sad that this thievery goes on!
I hope you enjoy your new XR-100 as much as I enjoy mine.
You make a good point - EACH Rifle is an individual and no telling the preferences or accuracy from one Rifle to another even though they may be the same brand and model!
Hold into the wind
